This study presents a simple procedure to correct hydraulic conductivity (K) estimates from slug tests in small wells. The method accounts for frictional losses, improving K accuracy in highly permeable aquifers.

Area of Science:

  • Hydrogeology
  • Environmental Science
  • Geotechnical Engineering

Background:

  • Slug tests are common for estimating hydraulic conductivity (K).
  • Discrepancies exist between K estimates from small-diameter and large-diameter wells.
  • Frictional losses in small pipes are a primary cause of these discrepancies.

Purpose of the Study:

  • To present a simple procedure for correcting hydraulic conductivity (K) estimates from slug tests.
  • To address discrepancies caused by frictional losses in small-diameter installations.
  • To improve the accuracy of K estimates in highly permeable aquifers.

Main Methods:

  • Incorporating frictional losses into existing slug test models.
  • Developing a straightforward procedure for K estimate correction.

  • Validating the procedure with field-tested slug test data.

    • Main Results:

    • A validated procedure for correcting hydraulic conductivity (K) estimates was developed.
    • The procedure effectively accounts for frictional losses in small-diameter wells.
    • Slug tests in small-diameter installations can provide detailed spatial K variations.

    Conclusions:

    • The proposed procedure accurately corrects hydraulic conductivity (K) estimates from slug tests.
    • This method enhances the reliability of hydrogeological assessments in permeable formations.
    • Small-diameter slug tests offer valuable insights into aquifer heterogeneity.
